GATEv Fon DUMP-CARS.

Specification of Letters Patent.

Patented Dec. I, 1908'.

.Application filed May`13, 1908. Serial No. 432,622.

To all 'whom it may concern:

Be it known that I, THOMAS R. MGKNIGHT, a citizen of the VUnited States, residing at Aurora, in the county of Kane and State of Illinois, have invented certain new and useful Improvements in Gates for DuJnp-Cars, of which the following is a specilication, reference being had to the accompanying drawmgs. v

. My invention relates to dump-cars of the type in which the car-body is arranged to be tilted to discharge the load at the side, such cars usuallybeingarranged so that the load may be dumped at either side.

It has for its object to provide a new and im roved side-gate for, such cars which will necessary strength and rigidity to satisfacto- 'in which such cars lare usually employed. I accomplish this object as illustrated in the drawings and as hereinafter described.

What I regard as new is set forth inthe claims.

In the accompanying drawings, in which I have illustrated my improved side-.gate as applied to a dump-car' mounted so that it may be dumped at-either side of the car,- Figure 1 is a partial end view of a car, showing the car-body, the side-gates and mechanism for automatically holding up the gates when the 'car-body is tilted to permlt of the discharge of the load; and Fig. 2 is an enlarged cross-sectional view of one of the gates. y

Referring to 'the drawings,3 indicates the car-body which is mounted on supports 4 pivoted at 5 upon 'the truck, as. illustrated and described in Patent No. 612,2B3,.`granted to me October 11, 1893. 6 indicates the sideates, which, as shown in Fig. 2, are compose of two parallel plates 7-8 secured together .at

projecting lianges 10 of said Z-bars being riveted or otherwise ixedlysecured along the margins of the plate 7 while the vinwardlyi projectin flanges 11 of 'said vZ-bars are secured at t e side edges of the plate 8 and'be'- tween the plates 7 an'dS, as shown in Fig. 2.. The lates 8 with the' Z-bars thus reinforce the p ates 7 which-directly support the load, thus providing a very strong and rigid but, nevertheless re atively light construction.

lThe side-gates 6, vin the .construction their side edges' by`-. Z-bars 9 oppositely arranged,I the outwardly-- such that when the car-body is tllted to dump the load at either side the end-gate at suc side of the car is held up while the car-body is tilted, thereby permitting the load to discharge. p

It will be noted thattwhile my improved side-gates are shown and-described in connection with a dump-car of the type referred to, they may be employed in other forms or other styles of cars and may also be used as end-gates, or in other equivalent situations.

That which I claim as my invention, and desire to secure by Letters Patent, is,-

1. The combination of a car-body, a gate comprising separated parallel plates xedly connected together, and means pivotally connecting the end portions of the gate with the car-body so that it may be swung `into and out of operative position.

2. The combination of a carbody,fa Gate com rising separated parallel plates, Z-liars rigi 1y connecting the side edges of said plates together, and means pivotally connectin the" end portions of the gate with the car-bo Ay so that it may be swung into and out ofoperative position.

3. The combination of a car-body, a gate comprising separated parallel plates, oppositely-disposed Z-bars rigidly connecting the side edges of said plates together, and means pivotal y connectin the end ortions of the gate with the car ody so t at it may be swung into and out of operative position.

' 4. The combination of a car-body, a ate comprising plates set a ldistance apart, ars secured to the side edges 'of said plates and serving to rigidly connect. them together, kand means pivotally connecting the end portions of the gate with'the car-body so that it may position.

5. The combination with a dump-car. of agate comprising plates set a distance apart, bars secured .to the side edges of said plates and serving to rigidly connect them together, and means pivotally connecting the end portions of the gate with the car-body sp that it may be swung into and out of operative position. p

6. The combinationl with a dump-car, of

'a gate comprismglplates set a distance a art, gate out of operative position when the carbars secured to t e side edges of said p ates body is dumped.

and serving to rigidly connect them together,

means pivotally connecting the end portions l' THOMAS R" MCKNIGHT 5 of the gate with the car-body so that it may Witnesses:

be swung into and out of operative osition, MILES T. BABB,

, and means for automatically yhol ing the FRANCES B. FLYNN.
